Answer:

A.) 64

Step-by-step explanation:

The first step is identifiying the original price of the shoes and the discount

Next you will decide what type of equation you will need. For this situation, you would need a subraction equation.

80 - 20% = ?

If you choose to slove with a calculator, don't put 0.2 in the place of 20%. We dont do this because it will result in a different answer. 80 - 0.2 = 79.8.

Now we solve the problem

80 - 20% = 64

=translated*to*form*f((x))shown*on*the*graph*0.

f((x))=+6+1

f((x))=x-6+1

f((x))=x+6-1

f((x))=3x-6-1

=8

=10

=x

BC and DF are parallel lines. B is a point on AD and E is a point of DF. BD=BE. work out angle DBE give a reason. ITS ON MATHSWA
zloy xaker [14]

Answer:

(Angle DBE) ∠DBE = 50°

Step-by-step explanation:

It is crucial for us to be able to interpret plane geometry related question in order to solve them efficiently.

From the question given; we have analysed and come up with a diagrammatic expression and mathematical solution that clearly explains the question .

Given that

BC and DF are parallel lines.

B is a point on AD  

B is a point on AD

BD=BE

work out angle DBE and give a reason.

The diagram can be seen in the attached image below.

SInce ∠BD = ∠DE

Then triangle BDE is an isosceles triangle. In an isosceles triangle ; two sides are equal in length.

The sum of angles in an isosceles triangle = 180° (sum of angles in a triangle)

So;

∠BDE + ∠BED + ∠DBE = 180° (sum of angles in a triangle)

From the diagram; we will see that ∠ABC = ∠BDE  (corresponding angle)

Since ; ∠ABC is not given and which is needed to solve this question.

Let's just assume that ∠ABC is 65° , the main thing is to be able to interpret and understand the concept of the question.

Now;

Since

∠ABC = ∠BDE  

∠ABC  = 65°

∠BDE  = 65°

Again;

∠BDE + ∠BED + ∠DBE = 180° (sum of angles in a triangle)

∠BDE will be aso equal to  ∠BED ; this is because since the length of the opposite sides of the isosceles triangle are equal, their angles will also be equal.

Therefore;

65° + 65° + ∠DBE = 180° (sum of angles in a triangle)

130 ° + ∠DBE = 180° (sum of angles in a triangle)

∠DBE = 180° - 130°

∠DBE = 50°

Can 1/2 be written as a terminating decimal?
igor_vitrenko [27]
Yes it can and the answer would be 0.5

Terminating decimals are numbers that never stop going after the period. Such an example would be 10/3 which would give 3.333333 indefinitely. 1/2 gives a whole number, that is, 0.5
